The power has gone out at the Superdome during the third quarter of the Super Bowl.

Minutes after Baltimore scored on a 109-yard Jacoby Jones kickoff return to take a 28-6 lead, several banks of arena lights went out in the dome. Emergency lights went on but play was immediately halted.

Players are standing on the field but when it became clear it would not be a brief outage, they left the field and went to the sideline.

Several of the Ravens are sitting on the field, stretching to try to keep loose.

Lights are on outside the dome; the outage appears confined to the arena.

Just Beyonce, then Kelly Rowland and Michelle Williams to bring back Destiny's Child.

Beyonce sang a medley of hits, including "Crazy In Love," `'Baby Boy" and "Single Ladies." She also danced in front of a screen using multiple images of herself as a backup dancer when she wasn't backed by her all-female band and nearly two dozen dancers.

But when Rowland and Williams sprang up from trap doors onstage, the world got the performance it was anticipating.

Not surprisingly, the show dominated worldwide Twitter trends as the second half began.

Raise your hand if you had David Akers scoring all of San Francisco's points in the first half.

Yeah, didn't think so.

San Francisco's much-maligned kicker made two field goals, accounting for the 49ers' only points in what's shaping up to be a Baltimore rout. The Ravens have a 21-6 lead at halftime, and no team has ever come back to win the Super Bowl after trailing more than 10.

The Baltimore Ravens are making a serious case for just awarding the Lombardi Trophy at halftime.

Joe Flacco threw a 56-yard touchdown pass to Jacoby Jones, who made San Francisco cornerback Chris Culliver look silly once again. This time, though, it wasn't for anything Culliver said.

Jones caught the ball at the 9, and Culliver completely whiffed on the tackle. Safety Dashon Goldson wasn't much better, running right by Jones when he came in to help. Jones then sprinted untouched into the end zone.

It was the 11th touchdown pass this postseason for Joe Flacco, matching an NFL record.

And, just a reminder, no team has ever been down by more than 10 points and come back to win the Super Bowl.
